Abstract: In the present investigation, the effects of expectation of success, high (HES) and low (LES), and audience presence versus absence on complex task performance were examined. Sixteen male and 16 female college students were instructed to perform on a complex memory task. Following recall, subjects were told that they performed poorly or superbly and were then instructed to perform on a second similar task. Subjects were assigned to either an audience or to an alone condition. Furthermore, subjects completed effort, expectation, and arousal scales before commencing on tasks I and II. The analysis of covariance revealed a significant expectation x audience presence interaction. Scheffe' post hoc comparisons indicated that alone condition LES subjects (AL-LES) performed significantly better than audience condition LES subjects (AUD-LES) while the performance of alone condition HES subjects (AL-HES) did not significantly differ from audience condition HES subjects (AUD-HES). Although neither of the comparisons within audience presence reached significance, the form of the interaction indicated that within the alone condition, the performance of LES subjects was superior to that of HES subjects. On the contrary, within the audience condition, the relationship was reversed. The verbal data were inconsistent with the behavioral data. The data were discussed in relation to a number of theoretical positions.
